Answer:
27 times
Step-by-step explanation:
the volume of the second cube would be 3³ = 27 times as great as the first cube, since multiplying the length by 3 would increase it on all sides of the cube.
the volume of the first cube is 10³, or 10 × 10 × 10, which is equivalent to 1000cm³.
the volume of the second cube is 30³, or 30 × 30 × 30 = 27000cm³, which is 27 times of 1000cm³.
i hope this helps! :D
